  • 摘要: 延长积累时间可以有效提高无源雷达的目标探测能力,但是对于高速机动目标,其速度、加速度、第二加速度等因素导致现有的检测算法在积累过程中发生距离徙动(RM)和多普勒频率徙动(DFM),使得目标检测性能恶化。该文针对无源雷达中变加速运动目标的长时间相参积累问题,提出一种基于相邻互相关函数(ACCF)-参数化中心频率-调频率分布(PCFCRD)-Keystone变换(KT)的相参积累算法(ACCF-PCFCRD-KT)。首先给出无源雷达中变加速运动目标的回波模型,分析了目标速度、加速度和第二加速度对相参积累的影响。针对目标第二加速度引起的多普勒频率弯曲,采用ACCF降低了距离和多普勒频率徙动的阶数,而后利用PCFCRD估计出目标加速度和第二加速度参数,在补偿了目标加速度和第二加速度引起的2次和3次徙动后,利用KT校正目标速度引起的线性徙动,并实现目标回波的积累。仿真结果表明,该算法可有效补偿无源雷达中目标运动导致的RM和DFM,对变加速机动目标的积累效果显著优于现有算法。
